is a Reptile?
(for the layman, not the scientist)
An air-breathing, vertebrate animal without hair or feathers, the body usually covered with a scaly impermeable (dry and scaly) skin. Reptiles are cold-blooded which means they get their heat from the outside environment and are torpid in cold weather (in contrast to the warm-blooded mammals and birds, and like the amphibians from which they evolved).
A key feature of reptiles and their descendants is the amniotic "closed egg" shared by mammals and birds, but not by amphibians. (Most mammals have since lost the shell retaining the infant in the body. Mammals also have the mammary gland for feeding their young milk.)
In some lizards and snakes and in some extinct reptiles (e.g., ichthyosaurs) the eggs are retained in the oviducts of the mother, sometimes with a placental connection, and the young are born alive. There are about 6,000 living species of reptiles.

After the storms, a most extraordinary discovery of a rare Kemp's Ridley Turtle, Lepidochelys kempii, washed up on Saltdean Beach, east Brighton, East Sussex, It was unbelievable as it is both the world's rarest sea turtle and thousands of miles out of its natural range, and unprecedented in the seas off Sussex.
Kemp's Ridley Turtles are listed as critically endangered by the World Conservation Union, with only 35 previous ecords of the Kemp's Ridley species in UK and Irish waters. According to the Marine Conservation Society the latest estimates suggest that only a few thousand adult females still nest on only one stretch of beach on the coast of the Gulf of Mexico.

A juvenile Loggerhead Turtle, Caretta caretta, was rescued after being washed up alive on Freshwater Beach West in Pembrokeshire, SW Wales. The 17 cm (6.7 in) male turtle was placed in a special quarantine tank at Bristol Aquarium where it is being treated before, hopefully, being returned to warmer Caribbean seas from where it had travelled across the Atlantic Ocean helped by the North Atlantic Gyre (Gulf Stream).
A sub-adult Loggerhead Turtle, Caretta caretta, was washed ashore dead at Splash Point, Worthing, Sussex in the afternoon. It was a rainy day and I cycled past this point west of the amusement pier, I noted a flock of twenty Crows on the shingle but I did not look down on the syenite rock sea defences or else I might have spotted it. Credit for the discovery goes to Andrew Cole who was photographing a landscape shot of the rocks in poor photographic conditions. This may be the first discovery of a Loggerhead Turtle off Sussex as it was unexpected and I have not got records of a previous discovery. The turtle was damaged with a missing flipper and it had died out at sea and had been washed along until landfall on to this small promontory.

teeth. They can also accidentally consume floating plastic
bags which will probably result in their death. Unlike other turtles
its carapace is not a hard shell (exoskeleton),
but is covered by a layer of rubbery skin strengthened by bony bits which
makes it look leathery. The turtle discovered in Falmouth Bay probably
swam across the Atlantic Ocean from a breeding site in Florida
or elsewhere in the Caribbean.
The IUCN classifies the Leatherback Turtle, Dermochelys coriacea, on the Red List as critically endangered.

Several fisherman have reported seeing a dead and decaying Loggerhead Turtle, Caretta caretta, about a metre and a half long to the east of the island of Herm in the Channel Islands. I do not believe a live individual of this species has ever been reported from the Channel Islands area. Occasional turtles have been seen before though and some of these were definitely Loggerhead Turtles.
9 January 2012
A juvenile 26.4 cm long Loggerhead Turtle, Caretta caretta, was discovered alive on the rocks at along Widemouth Bay on the north coast of Cornwall. This young ocean traveller was likely to have been washed in by the recent gales. Reports are rare in all months of the year, but especially so in the first months of the year when the sea is too cold for their survival around the British Isles.
December 2011 & 3 January 2012
Two young Kemp's Ridley Turtle, Lepidochelys kempii, was discovered on the shore at Tresilian Bay, near Llantwit Major, on the south Wales coast. These young turtles were discovered dead after the gales. These endangered turtles breed on the coasts of Mexico and are usually found in the Gulf of Mexico and were thought to have blown across the Atlantic Ocean. The turtles are likely to have perished in the cold seas.
A Green Turtle, Chelonia mydas, was discovered on a beach in South Ronaldsay, Orkney Islands, (ND 463 900) after the recent storms. Unfortunately it was freshly dead, but intact, so its remains were sent to Scottish Agricultural College Veterinary Laboratory at Inverness. The carapace measured 290 mm long by 280 mm wide.

A dead juvenile Loggerhead Turtle, Caretta caretta, beached alive at Putsborough, near Woolacombe, on the north Devon coast. It was rescued from the cold British seas and transferred to the Blue Reef Aquarium at Newquay, Cornwall. To the amazement of the discoverers Diana and Pauline Bussell, a little blue crab crawled out from underneath the dinner plate-sized shell of the turtle. This turned out to the alien hitch-hiker known as the Columbus Crab, Planes minutus, which occasionally gets washed up on the shore with floating driftwood and other pelagic debris. Another Loggerhead Turtle was discovered alive at Widemouth Bay, Cornwall, a few weeks earlier.

A Leatherback Turtle, Dermochelys coriacea, was found dead off the coast of Cornwall. It was spotted by a helicopter crew which was carrying out a survey for RNAS Culdrose. The turtle, which is the largest reptile in the world, had become entangled in lobster pot buoy ropes off Botallack, near Lands End. It was towed to shore at Cape Cornwall by the Sennen Inshore Lifeboat.
A group of seven Leatherback Turtles, Dermochelys coriacea, were spotted around the Isles of Scilly, south-west of Cornwall.

A Loggerhead Turtle, Caretta caretta, was discovered on Carbis Bay, Cornwall, and because it seemed to be impeded by a parasitic growth, it was taken to the Blue Reef Aquarium in Newquay.
This Leatherback Turtle, Dermochelys coriacea, measuring over two metres in length was washed up in Luce Bay near Port William, SW Scotland. It was alive when stranded, but it died shortly afterwards.
A Leatherback Turtle, Dermochelys coriacea, was spotted five miles south of Mevagissey off the south coast of Cornwall. This is an unusually early sighting which normally start appearing in UK waters in early summer.
Newquay resident Jo Leach reported the turtle after spotting it while out on her uncle’s crab potting boat.
“My uncle was using his binoculars to look out for the Fin Whales that had been reported over the weekend, when he saw something that he thought looked like a rock breaking the surface”, said Jo Leach, “We approached the object and cut the engines, and when we were about five metres away we could see it was a Leatherback Turtle. It gazed at us for a few minutes and then slowly swam off, as if it had had enough of looking at us!”
Vic Sell discovered a small turtle on Widemouth beach, Cornwall, but it disapeared before it could be identified.

A live Green Turtle, Chelonia mydas, was stranded on the west coast of Guernsey (Channel Islands) in the afternoon. Elliot Green, was playing football with his young son, discovered the turtle on Saline Beach and reported it to the Guernsey Society for the Protection of Cruelty to Animals (GSPCA). Geoff George and Yvonne Chauvel (in the photograph) collected the turtle, and after it had been treated by veterinarian John Knight, transferred it to the Guernsey Aquarium at St. Peter Port until arrangements can be made to release it into the sea at a suitable location (preferably warm water). This species of turtle inhabits tropical seas including the Atlantic coast of Spain and the Mediterranean Sea. It is only very rarely recorded in British seas.
The white spots are a species of turtle barnacle, which may have not been recorded before on the British list of marine (barnacle) species (MCS Directory).

With the swarms of jellyfish it is does not come as a suprise that a predatory Leatherback Turtle, Dermochelys coriacea, was seen by Ian and Joy Olford 50 metres from the shore off Polruan, Cornwall (SX 125511). The jellyfish Rhizostoma octopus was seen nearby and jellyfish are the principal diet of these turtles.
Donny Nicolson reported a dead Leatherback Turtle, Dermochelys coriacea, washed ashore on the Dale beach at Walls (west Mainland) in the Shetland Isles. It is decomposed and has probably been there some time although the carcass is still intact. It measured 6ft 4" from nose to tail. It was 7ft across the flippers. There were 7 ribs along its back, and the longest one measured 51" and was 39" across all 7. Approximately 4-5cwt. This is the twelfth recorded find from the Shetlands.

Subject: Leatherback turtle in the Firth of Forth
BDMLR Medics in Scotland spent much of the weekend on the trail of a Leatherback Turtle Dermochelys coriacia in the Firth of Forth. The turtle, measuring some 4-5 feet across, became the focus of a large scale operation which lasted throughout the weekend and continues today into the week ahead.
The reptile was first spotted on Friday afternoon some 30 miles up the Forth river towards the Stirlingshire town of Alloa, very close to the south Alloa jetty. It was soon identified as a Leatherback, the World's largest sea turtle and sole living representative of the family Dermochelyidae. A local SSPCA officer, Brian Calling, was first on the scene, but was unable to reach the turtle who had subsequently become corralled into the deeper waters of the forth by two fishing boats who had taken a passing interest in the unusual visitor.
A search of the area was coordinated to try and re-locate the turtle using 3 boats working together to cover a 30 mile stretch of the Firth from Stirling to the Forth Road bridge but to no avail. Whilst this suggested to some that the animal may have made its way back out to the open sea, the turtle could very easily have been missed. Resting turtles, for example, can remain submerged at the bottom of the water column for substantial periods of time, and certainly long enough for a searching boat to pass well overhead. In addition, the entire estuarine area of the firth is HUGE, and even the most systematic search of the area might prove elusive.
Leatherback turtles can attain weights of up to 1.5 tonnes. They are present mostly in August and September off the south and west coasts of Britain and Ireland and off the Shetlands, but this is not the first time the species has been recorded in the Firth of Forth. These turtles undertake extensive migrations to British waters as they follow swarms of jellyfish, the leatherback's main prey item. We are currently concerned about the food availability for this huge reptile at this time of year and in this location. If we are unable to catch the turtle, it may simply use up its food reserves if it remain trapped in the firth, confused by its unfamiliar new environment.
Scotland teams are equipped and standing by should the turtle reappear.
It was 14 November 2001 before it was discovered and photographed after an extensive and systematic search in small boats.

Bycatch of marine turtles in UK and Irish waters

TURTLE AWARENESS GROWS.
13 March 2001
The discovery at Holywell Bay today of a young Loggerhead Turtle, Caretta caretta, now being looked after by marine experts at the Blue Reef Aquarium in Newquay, has highlighted increasing awareness of this area's importance for turtles
Turtles feature prominently in the latest report from Seaquest South-West, the marine recording project being run by the Cornwall and Devon Wildlife Trusts.
This species was last seen in Cornwall in 1949 and only 26 have been sighted in Britain since records began in 1748. One of the Cornish turtles was the largest Kemp's Ridley ever recorded in the UK, with a shell measuring over 60 cm in length. Sadly, this animal was already dead and the other two died despite the efforts of the Blue Reef Aquarium to nurse them back to health.
Strict protection of its beach nesting sites in Mexico has resulted in rapid population growth for this highly endangered creature, which may be one of the reason why we are seeing these turtles more often, but the situation may be more complex as Philippa describes:
is possible that the change in the environment caused by global warming
may have initiated changes to the oceanic currents on which these animals
travel and feed, or it may be that the concerted conservation effort has
created sufficient population pressure that individuals or indeed groups
are cast out in search of new areas to feed and breed. It has been suggested
that it may just be that every population has a number of aberrant individuals
that make this journey, as an evolutionary mechanism for colonising new
areas, and that as the population increases this percentage represents
more individuals. It may even be that these animals are often near our
shores but only get washed up or spotted when we have large storms with
onshore winds. It is highly likely that the answer is found in a combination
of some of these factors."
By comparison, the huge Leatherback Turtle is almost a common sight in Cornish waters, with Colin Speedie of the Cornwall Wildlife Trust describing the behaviour of three such creatures on just one trip from the Scillies to Cornwall last summer.
According to the Trust's Education and Publicity Manager Mark Nicholson, this is further evidence that the leatherback is a significant part of the South-West's wildlife:
"These incredible creatures, often growing to over two metres in length, breed on tropical beaches but deliberately migrate thousands of miles to feed on the abundance of jellyfish supported by our cold waters. One of our first steps towards conserving them has been to make people aware that they are part of this area's wildlife. What's more, we think they must be present in quite large numbers if we can see them so regularly, bearing in mind the vastness of the sea, the fact that they spend most of their time submerged or partially submerged and the difficulty in spotting what little pokes above the surface when the sea is not totally calm."
The Cornwall and Devon Trusts are keen to increase their knowledge of Leatherbacks, both through sightings reported to Seaquest and through the development of radio-tracking and other research projects in co-operation with the Marine Conservation Society and others.
Local and global threats
While the South-West's Leatherbacks are thought to derive mainly from breeding sites in Central and South America, others hatch out in Africa and South-East Asia. Cornish student Denise Hooper gained an insight into the problems faced by turtles in their nesting areas when she visited Malaysia last summer to carry out a research project. There she discovered that harassment of nesting turtles by exploitative tourist businesses had driven the creatures away from some areas, leading to the collapse of the local economy, and she was struck by the parallels with the South-West:
"Tourism was the primary industry in Rantau Abang, with the turtles as the main resource. This irresponsible exploitation has almost eliminated that resource and the economy is suffering greatly. There is currently a problem with harassment of marine life in the South-West and people need to learn a lesson from examples like Rantau Abang to prevent it happening here. Marine life is a very important tourist attraction and we need to ensure that it is not scared away."
While many of the threats to Leatherbacks, such as damaging and disturbing nesting beaches or taking eggs and adult turtles for food, relate to the tropics, the Trusts point out that there is much to be done to make our own waters safer for turtle populations, as Mark Nicholson explains:
"We have to continue to monitor fishing methods, for example, as some are much more dangerous to turtles than others. The problem of oil pollution also affects turtles and all other marine life both at home and abroad. Another global problem which particularly affects leatherbacks is that of marine debris. The creatures often mistake plastic bags for jellyfish and end up dying a slow and painful death due to blockage of their guts."

The tenth live Leatherback Turtle, Dermochelys coriacea, in Shetland waters was found tangled in creel ropes in Basta Voe (Yell) during the afternoon. Despite attempts to free it unharmed the animal was so badly caught it had to be brought ashore to be released.
Once ashore and untangled it became torpid and appeared unable to return to the sea. It was therefore taken to the Wildlife Sanctuary at Hillswick for rehabilitation where, even after an examination by a vet and treatment for abrasions from the creel ropes, it eventually died.

Subject: A third Leatherback Turtle
A large (2 metres long) Leatherback turtle has just been reported by Brixham Coastguards. It was sighted a quarter mile off Start Point, Devon this afternoon.
This is the third one in ten days - the first was off the Runnelstone (rescued by fishermen as reported to the group by Ray Dennis), the second was about 12 miles due south of Plymouth (brought to Doug Herdson of the National Marine Aquarium - unfortunately drowned). Number three seemed to have no problems, and may it remain trouble-free.
A large Leatherback Turtle, Dermochelys coriacea, was discovered dead, entangled in the nets of a fishing boat off Plymouth in the English Channel. The turtle was nearly 2 metres in the length and the turtle was estimated to weigh about 150 kg (300-400 lb).
Leathery Turtle – 29th June 2000-07-03
Late afternoon of Thursday 29th June, the F.V. Our Louise (Skipper Rod Townsend) found that their bottom set net had been dragged almost half a mile from its original position. The position was approximately 12 miles due south of Plymouth. On hauling the net a large turtle was found just below the surface entangled in the dan line going down to the net which was in 45 metres of water. When brought aboard it was found to be dead. It was brought in to Plymouth Fish market where it was photographed and examined by National Marine Aquarium staff (and later by the local press). It was subsequently taken by a fisherman and a local artist who will attempt to cast a model from it.
The animal generally appeared to have been in excellent condition with no scarring or epizooites. The only injuries were a small wound to the top of the head and some slight grazing of the carapace presumably from manhandling it aboard the vessel.
It was a uniform greenish black except for a pale pinkish area with black spots below the chin, on the neck and upper chest.
Total length 176 cm
Carapace length 137.5 cm
Head (to rear of skull) 29 cm
Front flipper (left, angle to tip) 84 cm
Rear flipper 40.5 cm
Tail 14 cm
I should welcome any opinions as to the age and sex of this specimen from those with experience of this species.

A report has been received of a Kemp's Ridley Turtle, Lepidochelys kempii, stranded alive in Wales, UK. It is currently being held in St. David's Oceanarium in Wales while arrangements are made for its return to Mexico. This turtle has only one wild breeding site in the Gulf of Mexico.
A young 30 cm long (one foot) baby Loggerhead Turtle, Caretta caretta, weighing 3 kg (6.6 lb), was discovered on a beach on Denmark's west coast by a nature warden and sent to Copenhagen Aquarium.
Loggerhead turtles, one of several endangered species of turtle, measure up to 110 cms (3.5 ft) and can weigh some 70 kg (154 lb) when fully grown.

Nigel Hunter discovered a Leatherback Turtle, Dermochelys coriacea, decomposing on Newborough beach on the Isle of Anglesey. The turtle was nearly 2 metres long and nearly a metre (90 cm) wide.
There is an island at Newborough which gets cut off from the mainland at high tide. It was on this section of beach. I was on holiday for the weekend on Anglesey Wales.
I live in Littleborough, Lancashire.
A Leatherback Turtle, Dermochelys coriacea, weighing 500 kg* was discovered alive but in a poor condition one mile off Roker, Sunderland, in the north-east of England. It was captured but died shortly afterwards. The turtle measured 2.1 metres (7 ft) long and 1.5 metres (5 ft) wide. Turtles feed on jellyfishes and the abundance of jellyfishes is thought to be the reason for its occurrence. (* the original report estimated the weight at 750 kg)

ALeatherback Turtle, Dermochelys coriacea, was seen swimming in the sea off the southern end of Bressay (between the Ord and the Bard) in the Shetland Islands by John Tulloch this evening. It is the only the ninth live individual to be seen in Shetland waters and was estimated to be around 150 cm (5 feet) in length.
On 2 September 1999, a large turtle, estimated to be about 1 metre in length and was reported in Bluemull Sound, between Yell and Unst, in the Shetland Isles, by the crew of the Fetlar ferry.

Ryan Williams and Brett Jose (Cadgwith, Cornwall) spotted a 120 cm long Leatherback Turtle, Dermochelys coriacea, poke his head out of the water whilst they were fishing off Church Cove on the Lizard Peninsula in Cornwall. A Newlyn fishermen also spotted one near the Isles of Scilly .
My friends Tony Clancy and Steve Connor found a dead Leatherback Turtle washed up on Aveley Bay, Rainham, East London on the weekend of 28/29 November 1998, after which it was taken away for a postmortem.
The report indicates that
the turtle was first seen in bad health about 2 miles east of the Queen
Elizabeth Bridge/Dartford River Crossing on 26 October (the report later
gives this date incorrectly as 26 November), and what was assumed to be
the same turtle was found dead 27 days later at Tilbury on 22 November.
The turtle had a large gash thought to have been caused by a propeller, and the postmortem found a 11mm x 75mm fragment of plastic at the entrance to its stomach.
The paper includes an interesting discussion of this rare event, and covers ecology, other east coast records, possibilities for rehabilitation of stricken turtles, recommendations for dealing with stricken turtles etc.
A male Leatherback Turtle, Dermochelys coriacea, is landed by an Isle of Skye fisherman in Aros Bay, Uig. It is over 2 metres long.
"While gathering seaweed at La Mare slip yesterday, Mr J.P. Le Tourneur was surprised to find a queer looking creature moving about his load of vraic (seaweed).
This proved to be a turtle, and very much alive too! He took the reptile home and contacted Mr. Baal, the well known naturalist, who immediatley recognized it as a Hawksbill Turtle, Chelona imbricata. Local appearances of turtles are very rare and are probably due to freak weather conditions."
Vraic collecting has gone on for centuries in Jersey, and vraic was once used as a fuel. Time past on the outlying reefs it would be gathered and burnt the ashes being sold as fertiliser. At present the government pays for the collection of vraic washed up, for use as a fertiliser on local fields.

I'm compiling a table of information on satellite transmitter attachment methods for hard-shelled sea turtles. If you are willing to share your information please email me (email@example.com) the following information for each transmitter you have used. Everyone will be acknowledged for their contribution. Thanks for your help.
1. Species the transmitter
was attached to
2. Approximate age class/size of your turtle (juvenile, sub-adult, adult)
3. Attachment method (e.g. epoxy, resin, etc.)
4. Transmitter longevity/duration
5. Information regarding the final fate of the transmitter (e.g. unknown, retrieved, etc.)
